This is a language support extension of mimium, an infrastructural programming languge.
This extension provides a syntax highlight for mimium source files (which have .mmm extension), and basic error reporting feature.
Also, this extension works as the easiest installer of mimium compiler and standard libraries. The extension automatically download the latest release from Github Release into ~/.mimium. To use enhanced highlighting support and error reporting feature, the language server needed to be installed. The server is installed together with the compiler(mimium-cli) by this extension.
You can play opening mimium file on the editor, by the editor action button(right side of the file tabs) or the command palette (Cmd+Shift+P => "Run opening file").
